Effect of Alternating Pumping of Two Reactants into a Microchannel on a Phase Transfer Reaction

Alternating pumping of two reactants into a microchannel was found to provide, in comparison with batch processes, a more effective mixing and an increased yield for a particular organic reaction which uses a phase transfer catalyst. The superiority of the microreactor method increased with the frequency of alternation of the pumping of the two liquids.
